Apparatus and method for storing and playing content in a multimedia streaming system

Abstract

Apparatus for transmitting media content in multimedia streaming system is provided. Apparatus includes a transceiver configured to receive a request for the media content; and transmit a plurality of segments regarding the media content, wherein the plurality of segments comprises an initialization segment (IS) and a media segment (MS), wherein the IS includes a moov box and a stsd box, wherein the stsd box includes sample description entries required to decode all representations within a representation group, and wherein each sample description entry in the stsd box corresponds to coding information of a media component in each of the representations, wherein the MS includes a moof box including a sample description index and a mdat box including media data, and wherein a value of the sample description index is an index of one of the sample description entries in the stsd box.

What is claimed is: 
     
       1. An apparatus for transmitting media content in a multimedia streaming system, the apparatus comprising:
 a transceiver 
 configured to: 
 receive a request for the media content; and 
 transmit a plurality of segments regarding the media content, 
 wherein the plurality of segments comprises an initialization segment (IS) and a media segment (MS), 
 wherein the IS includes a moov box and a stsd box, wherein the stsd box includes sample description entries required to decode all representations within a representation group, and wherein each sample description entry in the stsd box corresponds to coding information of a media component in each of the representations, 
 wherein the MS includes a moof box including a sample description index and a mdat box including media data, and 
 wherein a value of the sample description index is an index of one of the sample description entries in the stsd box. 
 
     
     
       2. The apparatus of  claim 1 , wherein the transceiver is further configured to
 transmit, to a client device, control information regarding the media content, 
 wherein the control information comprises information informing whether a concatenation of a plurality of segments results in a bitstream that conforms to a media format. 
 
     
     
       3. The apparatus of  claim 2 , wherein the information further informs whether the bitstream is playable by a player. 
     
     
       4. The apparatus of  claim 1 , wherein the plurality of segments includes track identifiers, and
 wherein the track identifiers for a same media content component are identical for each of the representations. 
 
     
     
       5. The apparatus of  claim 1 , wherein the MS comprises at least one moof box,
 wherein the at least one moof box uses movie-fragment relative addressing. 
 
     
     
       6. An apparatus for receiving a media content in a multimedia streaming system, the apparatus comprising:
 a transceiver 
 configured to: 
 transmit a request for the media content; and 
 receive a plurality of segments regarding the media content, 
 wherein the plurality of segments comprises an initialization segment (IS) and a media segment (MS), 
 wherein the IS includes a moov box and a stsd box, wherein the stsd box includes sample description entries required to decode all representations within a representation group, and wherein each sample description entry in the stsd box corresponds to coding information of a media component in each of the representations, 
 wherein the MS includes a moof box including a sample description index and a mdat box including media data, and 
 wherein a value of the sample description index is an index of one of the sample description entries in the stsd box. 
 
     
     
       7. The apparatus of  claim 6 , wherein the transceiver is further configured to
 receive control information regarding the media content, 
 wherein the control information comprises information informing whether a concatenation of a plurality of segments results in a bitstream that conforms to a media format. 
 
     
     
       8. The apparatus of  claim 7 , wherein the information further informs whether the bitstream is playable by a player. 
     
     
       9. The apparatus of  claim 6 , wherein the plurality of segments includes track identifiers, and
 wherein the track identifiers for a same media content component are identical for each of the representations. 
 
     
     
       10. The apparatus of  claim 6 , wherein the MS comprises at least one moof box,
 wherein the at least one moof box uses movie-fragment relative addressing.
